In my opinion, a system that combines LIDAR, GPS, and a pre-recorded map is not really doing SLAM. This scenario does not suffer from the "chicken and egg" problem which is a defining characteristic of SLAM. GPS and the pre-recorded map both make the problem much, much easier than SLAM in a GPS-denied, unmapped area. Maybe we are just arguing over terminology.
